Ouch! Sorry to hear about that! You'll have to stay away from the threads that make you laugh for a while I suppose.

Thinking about the speed humps - when we first started getting them they did have space on the side so you could at least partly avoid them, or only catch the bit that didn't stick up so much. But now, they build them so they go all the way across to the edge, or there are little gardens with concrete walls attached to the side. Nasty!
